How should you treat someone who has fainted?

Laying the person down and elevating their legs is the appropriate treatment for someone who has fainted because this position helps improve blood flow to the brain. When a person faints, it often results from a temporary drop in blood flow, usually due to factors like lightheadedness or dehydration. By lying down and raising the legs, gravity assists in returning blood to the upper body and head, potentially accelerating recovery.

Encouraging someone to drink water immediately may not be safe until they regain full consciousness, as they could choke or not be in a state to safely swallow. Leaving them sitting up could exacerbate the situation by preventing adequate blood flow to the brain, which could prolong their fainting state. Applying a cold cloth to their forehead may provide some comfort but does not address the underlying issue of blood flow and does not effectively aid in their recovery.
